Apparatus and method for servicing a well Full Description BACKGROUND The present invention generally relates to systems; Heals and methods for mixing and quantifying a support in fracturing fluid 118011109 to be injected into a blister hole. in the oil and gas industry; A subterranean formation© (i.e. a reservoir) is often treated (or stimulated) to enhance or maintain seeding productivity. usually; Ala vehicles and equipment are used at the well site during the treatment process. Stimulus processing processes can include; Jal blending units pump units cmanifold trailers acid injection units 8010 dled proppant transport units and other types of equipment for Numerous Possible Procedures Typically, each type of equipment or unit is mounted on its own vehicle or trailer, or combination of vehicles or trailers, and operated by a crew dedicated to that particular type of equipment. Blast header by setup and sizes of equipment required for a particular project Each vehicle type and corresponding crew must have sufficient space at the blistering site to access al during its corresponding procedure Downtime can occur between some operations while waiting for the Vo crews to arrive to process Specific procedures in sequence required during oil field operation In cihydraulic fracturing a fracturing fluid is injected into a borehole;it penetrates an underground formation and forces the fracturing fluid at pressure to crack the stratum or rock.A support is placed in the fracturing fluid thereby It is placed inside the crack to form a buttress to prevent the crack from locking up when it is done pressure release” providing improved flow of extractable fluids; Any gas oiling or ele Ye The success of hydraulic fracturing treatment is related to the crack conductivity which is the fluid capacity

B

To flow from the formation through the backing pad. In other words, the backing or die can have a high permeability relative to the formation in order for a fluid to flow with small resistance into the blister hole. It can increase the permeability of the supporting template by distributing the support and non-supporting materials inside the crack to increase the porosity inside the crack.

© Before injecting the fracturing fluid, led and other components of the fracturing fluid may be mixed. Hydraulic fracturing operations can mix and pump over VY 1,000 tons of prop or dry ingredients/day; at a well site. The prop is often stored in silos or other types of units on site; Ally The prop connects to a hopper attached to a mixing unit. Then the prop is quantified from the hopper to the mixer.

0 dry ingredients; jie supports; liquid ingredients; Jie types of Ja can be mixed into the fracturing fluid; It is often referred to as eslurry mortar in a mixer. mixers; Such as the mixer mentioned in US Pat. No. 455,728,749 may have rope suspension elements having an annular shape with a concave upper surface. Upright blade members are fitted to the concave surface of this sling and an impeller member is attached to the underside of the sling ring.

5 “The suspension rope and the defense shall be placed inside a housing and attached to the end of a drive shaft driven by a motor mounted above the housing. A hopper is fitted over an inlet eye at the top of the housing; To introduce sand, solid particles or other dry ingredients into the housing. At the bottom of the housing there is an inlet for the suction of fluid or liquid components into the housing and the fluid-liquid mixture is drained through an outlet hole in the housing. While the aforementioned mixer is running; The sand flows out of the hopper and falls on the rotating suspension rope

0 a through the eye of the entrance in the lodging. by the defense and the suspension rope that rotates at the same speed; The swirling effect of the impeller creates a suction force that draws liquid into a casing through the inlet of the suction eye. When the liquid is sucked into the casing it is pressured up by the impeller and mixed thoroughly with the sand which is forcefully pushed out; by centrifugal action; from the rope interlock. The sand-water mixture is then hauled out under pressure; through the outlet hole; From there it is carried to the pump unit and injected into the blister. some

blenders like that mentioned before; It can make the air inside the dry component drawn into the slurry. Other Jie Mixers those listed in US Patent No. 0714475 are designed to mix dry ingredients with fluid ingredients without drawing air into the resulting slurry. The dry ingredients are contained in a hopper mounted above the inlet eye of a housing member. The outlet eye of the hopper is placed above the inlet eye to provide an outside air exhaust space at this point for the mixer. The housing contains a sling rope and a defense member which is attached to the lower side surface of the sling rope. The impeller and lanyard are each attached to the lower end of the drive shaft which extends up through the housing inlet eye to a motor that drives the shaft. The suspension rope has a helical shape and a concave surface of its upper side 0 which faces towards the housing Ad. The lower side surface of the hanging rope has a groove, and the cavity defines an internal air exhaust space between the hanging rope and the impeller. The sling also has one or more internal air exhaust ducts which extend from the air exhaust space between the sling and impeller to the top side surface of the sling. To obtain the required pressure output between 0 kPa and 551 kPa; The suspension rope and the impeller can rotate at a speed between 1,701 and 5,001 revolutions/min. 1 The high rotational speed in combination with the abrasive nature of the proppant stirred by the impeller and suspension rope wears the impeller and suspension rope components and often causes mixer wear; Which necessitates frequent maintenance and rebuilding. In addition to the previous mixers providing a compressed output higher than the hydrostatic pressure; Tub blenders are also used. Tub mixers separate Yo mixing and pumping operations. Jay the stand mixer and the fluid to a large bowl which has a stirring mechanism; Flo Horizontal ribbon mixer or rotary pedal. The mixing of the dry component and the liquid component in this tub takes place at hydrostatic pressure due to gravity; A centrifugal pump then takes the fluid from the bottom of the sump and discharges it at a pressure of about 501 kPa to high pressure fracturing pumps or manifold trailers connected to the pumps.

Co Some mixers also use centrifugal pumps to open clean liquid ingredients into a closed tub with a hanging rope at the top. The centrifugal pump fully raises the pressure of the sump; The suspension rope is inserted and the dry component is mixed with the liquid component to make a slurry. The slurry then exits the trough at a discharge point tangential to the housing. The suspension rope inside the basin does not add energy to the slurry above the energy received from the centrifugal pump as a result of the centrifugal pump © raising the pressure of the basin. In any type of mixer used to make slurry; There are components that are subject to wear and tear due to the highly abrasive nature of the backing within the mortar. in addition to; Some mixers raise considerations associated with maintaining adequate discharge pressure for high-pressure pumps or manifold High-pressure pumps can be located at the blister site at a significant distance from the unit 00801010.0 The mixer is estimated to be more than 0 lbs.m away from the mixer. The drop in pressure through the hose extending between the mixer unit and the high-pressure pump or manifold can cause insufficient suction pressure conditions on high-pressure pumps and thus cause inadequate wear on them due to insufficient or cavitation formation. In a single mixer .be Mixers that are typically used to mix fracturing fluid components are fiber products that are difficult to handle and quantify conventionally at desired concentrations usually with Lan reliability problems that Jods .060760109 has in both stimulation and stimulation work. Cementation, fiber delivery and quantification systems, fiber jams in the quantifying equipment, and blockage of the load ducts. Thus an interstitial separator of the fiber component to the separate liquid is required to prevent _ occlusion and is not subject to a restrictive geometry of the current fiber ducts 00 General Description of the Invention Well stimulation system is desirable in one of the modes of the present invention; The stimulus system blisters in it.
